Reverse DNS Records List

By default the Reverse DNS Records list will show all records. Use the Search field to narrow down the result. Know that the Verified Status, Domain , and IP Address columns are sortable.

Record Type

A PTR record is used to perform reverse DNS lookups. A PTR record or pointer record maps an IPv4/v6 address to the canonical name for that host. Setting up a PTR record for a hostname in the in-addr.arpa domain that corresponds to an IP address implements reverse DNS lookup for that address.

For example, www.random-site.com has the IP address 122.0.3.16, but a PTR record maps 16.3.0.122.in-addr.arpa. It is always advisable to have a proper reverse DNS record (PTR) set up for your servers, especially when you are running a mail / smtp server.
